:D Yes, yes!! Puna, we call them coozies (or cool cups) and we print on them. For parties, weddings (seriously!), you name it. You would be amazed at the things people say right out loud on these things. We also print photos on them if wanted. We have them in all colors and you're right, they look like cardboard (especially in this image), but they're foam rubber - these are about 3/16", and are the less expensive ones. We also have the more expensive ones that are not folded flat but they don't make heart shapes. :)
